1 Claim. (Cl. 153-54) This invention relates to Vises, and in particular to a vise especially adapted for performing multiple operations on metal work members, particularly tubes, rods, straps and bars.

The particular object of the present invention is the v provision of a multi-purpose vise particularly adapted for the home craftsman to enable him to do relatively complex metal working operations, particularly bending operations without requiring a great many expensive tools or a great amount of special equipment.

Another particular object of the present invention is metal members such as tubes, rods and strips, the arrangement including tool elements adapted for being mounted on a specially constructed machinists vise and cooperating with the vise to accomplish the forming of the metal members.

These and other objects and advantages of this invention will become more apparent upon reference to the following specification taken in connection with the accompanying drawings, in which:

Figure 1 is a perspective view of a machinists vise constructed according to my invention;

Figure 2 is a perspective view of the vise showing rollers mounted thereon for bending and forming strip material;

Figure 3 is a sectional view indicated by line 3-3 on Figure 2 showing the relationship of the forming rollers to each other and the manner in which they are mounted on the jaws of the vise;

Figure 4 is a view similar to Figure 2 but showing grooved-forming rollers mounted on the jaws of the vise so that tubing and rod material can be bent and rolled;

Figure 5 is a perspective view of the vise showing the jaws of the vise provided with adapters for forming straight bends in sheet metal;

Figure 6 is a perspective view of the vise showing it adapted for bending heavy bars and. the like;

Figure 7 is a perspective view showing the visewith a drilling attachment mounted thereon;

Figure 8 is a perspective view showing a specially con structed face plate adapted for being mounted in the vise jaws, particularly for use in connection with the drilling attachment of Figure 7;

Figure 9 is a perspective view showing a modification of my invention wherein adapter jaws are provided for being mounted on the jawsof a conventional vise;

Figure 10 is a perspective view showing the rollers of a tool according to my invention mounted on a plate which includes a movable jaw supporting one of the rollers so that the entire unit can be attached to a bench top or the like as a tool entirely separate from a vise;

Figure 11 is an elevational view showing a roller having a knurled surface thereon to provide a better grip on a workpiece; and

Figure 12 is a view like Figure 11 but showing a roller having a covering to prevent damage of a polished or soft metal surface.

Referring in somewhat more detail to the figures in the drawings, the vise illustrated in the several views in the drawings may comprise a base portion 10 adapted for being bolted to a work table and rotatably carrying a swivel platform 12 adapted for being locked to the base with a conventional lock mechanism 14.

Swivel platform 12 comprises an upstanding portion terminating at the upper end in the stationary vise jaw 16, and rearwardly of which, at a somewhat lower level, is an anvil part 18 comprising a vertical bore 20 with a clamping set screw 22 being provided for clamping bars in bore 20.

The portion upstanding from swivel platform 12 includes an opening for receiving the slide part 24 which, at one end, has integrally formed therewith the movable jaw portion 26 of the vise. A screw 28 is rotatably supported in the movable jaw portion of the vise and is threaded through a nut (not shown) carried on swivel platform 12 with a handle means at 34] of a conventional nature being provided for rotating screw 28 to move jaws l6 and 26 relatively.

As will be seen in Figure I, both of jaws 16 and 26 are formed with substantially fiat upper surfaces thereon as at 16a and 26a, respectively, and that the jaws are substantially heavier than are encountered in conventional machinists Vises.

In addition to the heavy, flat-topped configuration of the jaws, jaw 16 also has the spaced vertically threaded bores 32 therein, and jaw 26 has, in the center thereof, a vertical smooth bore 34.

The threaded bores 32 of jaw 16 are availed of for supporting on the said jaw various metal working tools adapted for cooperation with other tools carried by the movable jaw 26 by a vertical pin in the smooth bore 34 therein.

As will be seen in Figures 2 and 3, the rollers 36 may be mounted on stationary jaw 16 by the shoulder screws 38 which are threaded into bores 32 of the stationary jaw. The smooth bore 34 of the movable jaw 26 is similarly availed of for supporting a roller 40 receivable on a pivot pin 42 located in bore 34. A crank arm d4 fastened to the top face of roller 4th enables a workman to apply rotating effort to the said roller.

The arrangement of Figures 2 and 3 is adapted for bending and rolling of fiat or rectangular strips of metal or of other shapes of material which can be worked between flat rollers. In forming strips of metal in the arrangement of Figures 2 and 3, the metal is placed between the two rollers 36 and the single roller 40 and then the movable jaw of the vise is moved toward the stationary jaw thereof to apply a predetermined pressure to the metal strip. Then, upon rotating rollers ll), while simultaneously pushing axially on the metal strip if necessary, the metal strip can be fed between the rollers and at the same time be bent to a predetermined radius thereby.

Further bending of the metal strip over the same zone thereof to a smaller radius of curvature can be accomplished by adjusting the movable jaw of the vise still earer to the stationary jaw, and then again passing the metal strip between the rollers. In this way the metal strip can be bent to a configuration approaching the size of roller ill. It will be evident, of course, that a heavy strap may take several passes between the rollers, whereas a light strap may be bent in a single pass.

Referring now to Figure 4, an arrangement substantially identical to the one described in connection with Figures 2 and 3 is illustrated, except that in Figure 4 the rollers 46 that are mounted on the stationa'y jaw comprises grooves 43 which are of various sizes, while the roller Sil mounted on the movable jaw is similarly grooved as at 52.

The Figure 4 arrangement permits the bent and rolling of tubing and bars in the same manner as was described in connection with the bending and rolling of bars and straps in the Figures 2 and 3 arrangement.

The making of metal articles often requires the bend-- ing of metal sheet about a straight line. For this operntion I provide the arrangement of Figure 5, wherein the rollers referred to above are removed from the jaws of the vise and, instead, there are placed thereon the adapter elements so on the stationary jaw and on the movable jaw. One of the screws 38 is employed for holding adapter 6% on stationary jaw 16, while pin 42 is availed of for retaining adapter 623 on the movable jaw 34.

One of the jaws, forexample, jaw 60, has a V-shaped notch 64 therein, and the other adapter comprises a V-shaped projection 66 parallel therewith so that upon placing a flat sheet 68 between the adapters and forcing the adapter members together by rotating screw ii, the sheet 68 will be broken and bent around a sit ht line.

Preferably, the angle of groove 6 and projection 66 is somewhat less than 90", thus enabling the workman to arrive at a right angle bend in a sheet of metal by allowing for spring-back.

The Figure arrangement is particularly useful for relatively thin metal sheets, say, up to /64 of an inch in thickness or about 18 gauge, but many times it is desirable to bend heavy bars for the purpose of mal 1g support brackets, cranks and the like, and for bending members of this nature I prefer to use the arrangement of Figure 6 wherein the shoulder screws 38 are placed in the stationary jaw 16 without the rollers thereon, while a block 70 having a V-shaped end 72 is placed on pin 32.

With the Figure 6 arrangement, when a heavy bar as at 74 is placed between point 72 and screws con siderable force can be exerted to bend the bar by moving the movable jaw 26 toward the stationary jaw. The wide spacing between screws 33 and the point 721 of block '71? provides for a mechanical advantage considcrably in excess of what can be obtained by the Figure 5 arrangement.

Since the working of metals usually involves 1: e drilling of holes therein, my invention also provides a drilling arrangement for use with the vise, consisting of a bar 80 located in bore and upstanding at the roar of the vise, and on which is carried, an attachment S2 that includes a collar portion 34 adapted for being adjustably clamped to bar Ni and a slide part that can be moved vertically along bar 80 by manipulation of lever 88. The device includes a U-shaped strap 9i? adjustably secured to part 86 by screws 92, and which U-shaped part comprises a bracket 94 for receiving a hand drill or the like 96 to be retained thereon by strap 98.

The arrangement illustrated in Figure 7 permits readily converting the vise, according to this invention, to light drill press, permitting the rapid and accurate drilling of metal parts. A stop collar Mill on bar may also be provided to limit the downward travel of slide part 86 and the drill thereon, if desired. in connection with the drilling arrangement of Figure 7, i provide a face plate N2 as provided in Figure 8, which comprises the cleats or projections 1M welded or permanently affixed thereto, and forming surfaces that can be gripped be tween the jaws of the vise to support the face plate in the position illustrated in the dot-dash outline 1 66 extends the field of usage of the drilling attachment of Figure 7.

From the foregoing it will be seen that I have provided a metal working arrangement consisting of tool elements adapted for being detachably associated with a machin istss vise, and operating in cooperation with the machinists vise so that the normal functions of the vise can be availed of for making the metal working tools more useful and effective.

The particular vise illustrated has two threaded bores in the stationary jaw and one smooth bore in the movable jaw, but it will be appreciated that this arrangement could be inverted with the threaded bores in the movable jaw and the smooth bore in the stationary jaw, if desired. Also, for larger siZe vises, it may be desirable to include more bores in one or both jaws, with any suitable number or all thereof threaded, if necessary.

Referring to Figure 9, the arrangement shown therein comprises a substantially conventional vise having the roller means 112 on the stationary jaw of the vise mounted on a bracket 114 which is adapted for being detachably secured to the jaw of the vise and by the clamp screws 116.

Similarly, the movable jaw of the vise, which carries the roller means 118, is provided with a detachable bracket supporting the said roller means, and which bracket is likewise provided with clamp screws 122.

The Figure 9 arrangement shows my invention arranged so that the owner of a conventional vise can purchase the tools according to this invention, other than the drilling attachment, and use them in connection with his present vise without the expense of purchasing a special vise construction. The brackets of the Figure 9 arrangement could be arranged to be substantially universally adaptable for clamping on the jaws of both the large and small vises, as well as other jaws of vises of varying designs as are produced by different manufacturers. Similarly to the other previously described modifications, the roller means attached to the brackets in the Figure 9 construction could be detachable therefrom so that they could be replaced by other tools of the nature disclosed hereinbefore.

In Figure 10 I show how a plate 124 can be provided with slide 126 adapted for actuation by the crank-operated screw 128 for moving the slide inwardly and outwardly of its guide slot 130. Screw 128 is threaded through plate 126 and is rotatably supported by plate 124 but held therein against axial movement. Plate 124 is adapted for securing to a bench top and could be used separately from the vise. The plate 124 could detachably carry tool means, such as the rollers 132, while the slide 126 could detachably carry tool means, such as the crank-operated roller 134.

At certain times it might be advisable to knurl one or more of the rollers, preferably the driven roller, as indicated at 136 in Figure 11, and in other cases, particularly where working polished metals or soft metals such as some of the aluminum alloys, it might be advisable to provide the rollers with resilient and non-abrasive cover means as at 138 in Figure 12.

It will be understood that, while the drawings show the double rollers as being mounted on the stationary jaw and the single driven roller as being mounted on the movable jaw, this arrangement could be inverted so as to have the single roller on the stationary jaw and the double rollers on the movable jaw, and this inverted arrangement might, in fact, be preferable in case the rollers were quite large and the material being worked was of such a size that the driven roller was necessarily driven back.

In either case, or in the case of the invention as illustrated, the advantage would obtain that, with the single roller mounted on the stationary jaw, the work passing between the rollers and bent thereby would tend to curve away from the operator, and thus this inversion would provide a convenient arrangement in any case.

It will be understood that this invention is susceptible to modification in order to adapt it to difierent usages and conditions and, accordingly, it is desired to comprehend such modifications within this invention as may fall within the scope of the appended claim.

I claim:
